RESUMEN
The 2023 monkeypox (mpox) epidemic was caused by a subclade IIb descendant of a monkeypox virus (MPXV) lineage traced back to Nigeria in 1971. Person-to-person transmission appears higher than for clade I or subclade IIa MPXV, possibly caused by genomic changes in subclade IIb MPXV. Key genomic changes could occur in the genome's low-complexity regions (LCRs), which are challenging to sequence and are often dismissed as uninformative. Here, using a combination of highly sensitive techniques, we determine a high-quality MPXV genome sequence of a representative of the current epidemic with LCRs resolved at unprecedented accuracy. This reveals significant variation in short tandem repeats within LCRs. We demonstrate that LCR entropy in the MPXV genome is significantly higher than that of single-nucleotide polymorphisms (SNPs) and that LCRs are not randomly distributed. In silico analyses indicate that expression, translation, stability, or function of MPXV orthologous poxvirus genes (OPGs), including OPG153, OPG204, and OPG208, could be affected in a manner consistent with the established "genomic accordion" evolutionary strategies of orthopoxviruses. We posit that genomic studies focusing on phenotypic MPXV differences should consider LCR variability.

Ataxia-telangiectasia (A-T) is a disease caused by mutations in the ATM gene (11q22.3-23.1) that induce neurodegeneration Sasihuseyinoglu AS et al. Pediatr Allergy Immunol Pulmonol 31(1):9-14, 2018, Teive HAG et al. Parkinsonism Relat Disord 46:3-8, 2018. Clinically, A-T is characterized by ataxia, mucocutaneous telangiectasia, immunodeficiency, and malignancy. Movement disorders have been the most described and well-studied symptoms of A-T. Other studies have reported visuospatial processing disorders, executive function disorders and emotional regulation disorders, which are clinical manifestations that characterize cerebellar cognitive affective syndrome (CCAS) Choy KR et al. Dev Dyn 247(1):33-46, 2018. To describe the neurocognitive and emotional state of pediatric patients with ataxia-telangiectasia and to discuss whether they have cerebellar cognitive affective syndrome. This observational, cross-sectional, and descriptive study included 9 patients with A-T from May 2019 to May 2021. A complete medical history was retrieved, and tests were applied to assess executive functions, visual-motor integration and abilities, language, psychological disorders, and ataxia. Six girls and 3 boys agreed to participate. The age range was 6 to 14 years. The participants included five schoolchildren and four teenagers. Eight patients presented impaired executive functioning. All patients showed some type of error in copying and tracing (distortion) in the performance of visual perceptual abilities. Emotional disorders such as anxiety and depression were observed in six patients. Eight patients presented with dyslalia and impairments in word articulation, all patients presented with ataxia, and seven patients used a wheelchair. All patients presented symptoms consistent with CCAS and had variable cognitive performance.

Most patients with X-linked agammaglobulinemia are susceptible to infections, while some cases also suffer from inflammatory or autoimmune complications. We describe a patient with progressive encephalitis who improved after the use of immunomodulatory treatment with corticosteroids, fluoxetine, and nitazoxanide. In most of the cases the evolution of the progressive encephalitis is complicated and catastrophic. Based on our experience and the review of the literature, we propose the use of this combined treatment to control this devastating complication.

West Nile Virus (WNV) is a mosquito vector-borne zoonosis with an increasing incidence in Europe that has become a public health concern. In Spain, although local circulation has been known for decades, until 2020, when a large outbreak occurred, West Nile Virus cases were scarce and mostly occurred in southern Spain. Since then, there have been new cases every year and the pathogen has spread to new regions. Thus, monitoring of circulating variants and lineages plays a fundamental role in understanding WNV evolution, spread and dynamics. In this study, we sequenced WNV consensus genomes from mosquito pools captured in 2022 as part of a newly implemented surveillance program in southern Spain and compared it to other European, African and Spanish sequences. Characterization of WNV genomes in mosquitoes captured in 2022 reveals the co-circulation of two WNV lineage 1 variants, the one that caused the outbreak in 2020 and another variant that is closely related to variants reported in Spain in 2012, France in 2015, Italy in 2021-2022 and Senegal in 2012-2018. The geographic distribution of these variants indicates that WNV L1 dynamics in southern Europe include an alternating dominance of variants in some territories.

Tuberous sclerosis complex (TSC) is a genetic disorder, frequently characterized by early dermatological manifestations. The recognition and adequate description of these dermatological manifestations are of utmost importance for early diagnosis, allowing for the implementation of therapeutic and preventive measures. Fibrous cephalic plaques (FCPs) are considered a major diagnostic criterion for TSC, as FCPs are the most specific skin lesions of TSC. The localization, consistency, color, and size of FCPs vary widely, which can cause diagnostic delay, especially in patients with atypical presentations. The present report describes a female TSC patient with a confirmed heterozygous pathogenic genotype, NG_005895.1 (TSC2_v001): c.2640-1G>T, who presented with uncommon large and bilateral FCPs causing bilateral ptosis and marked with hyperostosis of the diploe that generated an asymmetry of the brain parenchyma. Differential diagnoses considered initially in this patient due to the atypical FCPs are described.
RESUMEN
This ecological study described the effect of the COVID-19 pandemic and socioeconomic development on the use and profile of urgent dental care (UDC). UDC rates per 100,000 inhabitants before (from March to June 2019) and during (from March to June 2020) the COVID-19 pandemic in 4,062 Brazilian municipalities were compared. Data were collected from official sources. COVID-19 mortality and hospitalization rates were indicative of levels of lockdown and Human Development Index (HDI) indicated socioeconomic development. Multiple logistic regression and relative excess risk due to interaction (RERI) were used for statistical analyses. The Student t-test was used to compare changes in the profile of UDC causes and procedures in the two periods. Lower UDC rates were found in 69.1% of municipalities and were associated with higher HDI (OR = 1.20; 95%CI: 1.01; 1.42). Mortality had OR = 0.88 (95%CI: 0.73; 1.06) for municipalities with HDI < 0.70 and OR = 1.45 (95%CI: 1.07; 1.97) for municipalities with HDI > 0.70. RERI between HDI and COVID-19 was 0.13 (p < 0.05). Municipalities with greater primary health care coverage had a smaller reduction in emergency rates. Endodontic treatment and dental pain were the most frequent factors both before and during the pandemic. The percentage of UDCs due to pain and soft tissue damage, as well as temporary sealing and surgical procedures, increased. Socioeconomic variables affected UDC rates during the most restrictive period of the COVID-19 pandemic and should be considered in the planning of health actions in future emergencies.

Antecedentes y objetivo: La elevada demanda asistencial sanitaria realizada por las personas trans en los últimos años ha dirigido el foco de la investigación hacia el estudio de sus aspectos clínicos y sociodemográficos. Este trabajo tuvo por objetivo comparar y analizar algunas variables sociodemográficas en personas trans en 2 períodos temporales: el período de inicio de funcionamiento de la unidad y el período más reciente. Materiales y método: Se comparó una muestra de 131 usuarios que asistió a la Unidad de Tratamiento de Identidad de Género del Principado de Asturias (UTIGPA) entre 2015-2019, con una muestra de 33 que acudió entre 2007-2009. Los datos se extrajeron de historias clínicas. Resultados: Respecto al período 2007-2009 entre 2015-2019 la ratio se invierte a favor de los hombres trans (HT). Los usuarios de ambos géneros solicitan consulta a edades más tempranas (especialmente los HT), provienen menos del extranjero, alcanzan una mayor cualificación educativa y laboral, presentan menos paro y solicitan más el cambio registral; y aunque las mujeres trans (MT) continúan siendo las que, mayoritariamente, se dedican a la prostitución y se autohormonan, en este período más reciente lo reportan menos y, además, conviven más acompañadas. Conclusiones: Se observan cambios en las variables sociodemográficas de los usuarios de la UTIGPA entre 2007-2009 y 2015-2019, en dirección a una mayor inclusión. No obstante, las condiciones sociodemográficas de las MT siguen en desventaja en comparación con las de los HT. (AU)
Background and objective: The high demand of assistance made by trans people in recent years has directed the focus of research towards the study of their clinical and sociodemographic aspects. The objective of this work was to compare and analyze some sociodemographic variables in trans people in two periods: the period when the unit began to operate and the most recent period. Materials and method: A sample of 131 users who attended the Gender Identity Treatment Unit of the Principality of Asturias (UTIGPA) between 2015-2019 was compared with a sample of 33 who attended between 2007-2009. Data were extracted from medical records. Results: Regarding 2007-2009, in 2015-2019 the ratio is inverted in favor of Trans Men (TM). Users of both genders request consultation at an earlier age (specially TM), come less from abroad, achieve higher educational and work qualifications, are less unemployed and request more name changes. And, although Trans Women (TW) continue to be those who are mostly engaged in prostitution and self-administration of hormones, in the most recent period they report it less and, furthermore, they live more accompanied tan in the past. Conclusions: Changes are observed in the sociodemographic variables of UTIGPA users between 2007-2009 and 2015-2019, in the direction of a greater inclusion. However, the sociodemographic conditions of the TW are still at a disadvantage in comparison to those of the TM. (AU)

BACKGROUND & AIMS: Exhaustion of CD8 T cells has been suggested to inform different clinical outcomes in Crohn's disease, but detailed analyses are lacking. This study aimed to identify the role of exhaustion on a single-cell level and identify relevant CD8 T cell populations in Crohn's disease. METHODS: Blood and intestinal tissue from 58 patients with Crohn's disease (active disease or remission) were assessed for CD8 T cell expression of exhaustion markers and their cytokine profile by highly multiplexed flow and mass cytometry. Key disease-associated subsets were sorted and analyzed by RNA sequencing. CD39 inhibition assays were performed in vitro. RESULTS: Activated CD39+ and CD39+PD-1+ CD8 T cell subsets expressing multiple exhaustion markers were enriched at low frequency in active Crohn's disease. Their cytokine production capacity was inversely linked to the Harvey-Bradshaw Index. Subset-level protein and transcriptome profiling revealed co-existence of effector and exhaustion programs in CD39+ and CD39+ PD-1+CD8 T cells, with CD39+ cells likely originating from the intestine. CD39 enzymatic activity controlled T cell cytokine production. Importantly, transcriptional exhaustion signatures were enriched in remission in CD39-expressing subsets with up-regulation of TOX. Subset-level transcriptomics revealed a CD39-related gene module that is associated with the clinical course. CONCLUSIONS: These data showed a role for the exhaustion of peripheral CD39-expressing CD8 T cell subsets in Crohn's disease. Their low frequency illustrated the utility of single-cell cytometry methods for identification of relevant immune populations. Importantly, the link of their exhaustion status to the clinical activity and their specific gene signatures have implications for exhaustion-based personalized medicine approaches.

BACKGROUND & AIMS: Despite recent translation of immunotherapies into clinical practice, the immunobiology of hepatocellular carcinoma (HCC), in particular the role and clinical relevance of exhausted and liver-resident T cells remain unclear. We therefore dissected the landscape of exhausted and resident T cell responses in the peripheral blood and tumor microenvironment of patients with HCC. METHODS: Lymphocytes were isolated from the blood, tumor and tumor-surrounding liver tissue of patients with HCC (n = 40, n = 10 treated with anti-PD-1 therapy). Phenotype, function and response to anti-PD-1 were analyzed by mass and flow cytometry ex vivo and in vitro, tissue residence was further assessed by immunohistochemistry and imaging mass cytometry. Gene signatures were analyzed in silico. RESULTS: We identified significant enrichment of heterogeneous populations of exhausted CD8+ T cells (TEX) in the tumor microenvironment. Strong enrichment of severely exhausted CD8 T cells expressing multiple immune checkpoints in addition to PD-1 was linked to poor progression-free and overall survival. In contrast, PD-1 was also expressed on a subset of more functional and metabolically active CD103+ tissue-resident memory T cells (TRM) that expressed few additional immune checkpoints and were associated with better survival. TEX enrichment was independent of BCLC stage, alpha-fetoprotein levels or age as a variable for progression-free survival in our cohort. These findings were in line with in silico gene signature analysis of HCC tumor transcriptomes from The Cancer Genome Atlas. A higher baseline TRM/TEX ratio was associated with disease control in anti-PD-1-treated patients. CONCLUSION: Our data provide information on the role of peripheral and intratumoral TEX-TRM dynamics in determining outcomes in patients with HCC. The dynamics between exhausted and liver-resident T cells have implications for immune-based diagnostics, rational patient selection and monitoring during HCC immunotherapies. LAY SUMMARY: The role of the immune response in hepatocellular carcinoma (HCC) remains unclear. T cells can mediate protection against tumor cells but are frequently dysfunctional and exhausted in cancer. We found that patients with a predominance of exhausted CD8+ T cells (TEX) had poor survival compared to patients with a predominance of tissue-resident memory T cells (TRM). This correlated with the molecular profile, metabolic and functional status of these cell populations. The enrichment of TEX was independently associated with prognosis in addition to disease stage, age and tumor markers. A high TRM proportion was also associated with better outcomes following checkpoint therapy. Thus, these T-cell populations are novel biomarkers with relevance in HCC.

Antecedentes y objetivo: El objetivo del presente estudio es investigar las características contextuales de la aparición de la disforia de género (DG) en menores trans.Materiales y método: Participaron todos los menores de edad que solicitaron consulta en la Unidad de Tratamiento de Identidad de Género desde marzo de 2007 hasta junio de 2019. Se procedió a la revisión de historias clínicas para la obtención de los datos. Se garantizó la confidencialidad.Resultados: Demandaron atención 64 menores, el 39,1% eran mujeres trans (MT) y el 60,9% hombres trans (HT). El rango de edad estuvo comprendido entre los 6 y los 17 años, con una media de 14,98. El 75% de los menores trans ubicaron el inicio de la DG en la infancia y el 25% en la adolescencia. La reacción de los progenitores fue de sospecha en un 55,6% de los casos y de sorpresa en un 36,5%. El 55,6% presentaron malestar psicológico importante previamente a acudir a la unidad.El apoyo familiar estuvo presente en el 57,1%. El papel de las redes sociales e Internet fue relevante para el 39,7% de la muestra. Tenían pertenencia o contacto con grupos de pares o asociaciones LGTBIQ el 44,4% de los menores. Se analizaron los resultados en función del género sentido.Conclusiones: Los menores continúan demandando atención en las unidades, sobre todo las MT. Aunque la DG aparece en ambos grupos fundamentalmente en la infancia, en la adolescencia es más frecuente en los HT. Los menores trans nacen, se desarrollan y construyen su identidad en un contexto determinado que está en interacción. (AU)

Este estudo ecológico descreveu como a pandemia da COVID-19 e o desenvolvimento socioeconômico afetaram o uso da assistência odontológica de urgência (AOU) e seu perfil. Comparamos taxas de AOU para cada 100 mil habitantes antes (de março a junho de 2019) e durante (de março a junho de 2020) a pandemia da COVID-19 em 4.062 municípios brasileiros. Os dados foram coletados de fontes oficiais. As taxas de mortalidade e internação pela COVID-19 indicaram níveis restritivos de lockdown e Índices de Desenvolvimento Humano (IDH) indicou o nível de desenvolvimento socioeconômico. Foram utilizadas regressões logísticas múltiplas e risco relativo de excesso devido à interação (RERI) para análises estatísticas. O teste t de Student foi usado para comparar alterações no perfil das causas e procedimentos da AOU nos dois períodos. As taxas de AOU foram menores em 69,1% dos municípios e associadas a IDH maior (OR = 1,20; IC95%: 1,01; 1,42). A mortalidade apresentou uma razão de chances de 0,88 (IC95%: 0,73; 1,06) para municípios com IDH < 0,70 e de 1,45 (IC95%: 1,07; 1,97) para municípios com IDH > 0,70. O RERI entre IDH e COVID-19 foi de 0,13 (p < 0,05). Os municípios com maior cobertura de atenção primária à saúde apresentaram menor redução nas suas taxas de emergência. Procedimentos endodônticos e dor dentária foram os fatores mais frequentes antes e durante a pandemia. O percentual de AOUs aumentou devido à dor, danos nos tecidos moles, vedação temporária e procedimentos cirúrgicos. Variáveis socioeconômicas afetaram as taxas de AOU durante o período mais restritivo da pandemia da COVID-19 e devem ser incluídas no planejamento de ações de saúde em emergências futuras.

El ERR entre el IDH y el COVID-19 fue de 0,13 (p < 0,05). Los municipios con mayor cobertura de atención primaria tuvieron una menor reducción de las tasas de urgencia. Los procedimientos de endodoncia y la causa del dolor dental fueron los factores más frecuentes tanto antes como durante la pandemia. Aumentó el porcentaje de AOU por dolor y daños en los tejidos blandos, así como el sellado temporal y los procedimientos quirúrgicos. Las variables socioeconómicas afectaron a las tasas de AOU durante el periodo más restrictivo de la pandemia de COVID-19 y deberían incluirse en la planificación de las acciones sanitarias en futuras emergencias.
RESUMEN
Radiography remains the most widely used imaging modality throughout the world. Additionally, while it has been demonstrated that a quality control (QC) program, especially in mammography, improves image quality, weekly technologist QC testing might be lacking even where there is clinical qualified medical physicist (CQMP) support. Therefore, the International Atomic Energy Agency (IAEA) developed simple QC phantoms that can easily be used on a regular basis (daily/weekly) for radiography and mammography. These are simple in design and use materials that are easily accessible in most parts of the world. A software application is also developed that automatically analyzes images and Digital Imaging and Communications in Medicine (DICOM) header information. It exports data to a comma-separated values (CSV) file that is read by a Microsoft Excel® spreadsheet for documentation and graphical analysis. The phantom and the software were tested in four institutions (in Costa Rica and the United States of America) both on computed radiography and direct digital mammography and radiography systems. Data were collected over a 3-year period. No corrective actions were taken on the data, but service was performed on two of the units. Results demonstrated noise that could be attributed to suboptimal placement of the phantom and incorrect data being put into the DICOM header. Preliminary evaluation of the IAEA methodology has demonstrated that it can provide meaningful QC data that are sensitive to changes in the imaging systems. Care must be taken at implementation to properly train personnel and ensure that the image data, including the DICOM header, are being correctly transmitted. The methodology gives the opportunity for a single CQMP to provide QC services even to remote sites where travel is prohibitive, and it is feasible and easy to implement.

OBJECTIVE: To present a case series of encephalitis patients with anti-N-methyl-D-aspartate receptor antibodies, attending two neurological referral centers in a three-year period. METHODS: A retrospective, descriptive, comparative study included child and adult patients in two neurological populations, positive for antibodies against the NR1 and NR2 subunits of the glutamate (NMDA) receptor in serum and CSF, as determined during a three-year period. RESULTS: Sixty-six patients were included (40 children and 26 adults). Male patients were more affected (M: F ratio was 1:0.6). No differences in progression or hospitalization time were observed between groups. In children, 35% of patients showed herpetic infection before autoimmune encephalitis (P = 0.01). Among viral prodromal symptoms, upper respiratory tract infection (P = 0.02) and fever (P = 0.001) predominated in children, while infectious gastroenteritis was more frequent in adults (P = 0.03). Among neuropsychiatric signs, mental confusion (P = 0.0001) and orofacial dyskinesia/oromandibular dystonia (P = 0.0001) were frequent in children, while emotional lability (P = 0.03), catatonia (P = 0.0001), and headache (P = 0.005) predominated in adults. The score in the modified Rankin scale on admission was higher in children (4.3 ± 0.8 vs. 2.2 ± 1.3, P = 0.0001), but at one-year of clinical follow up no significant differences were found. CONCLUSIONS: Male patients were predominantly affected in our population. One-third of all patients developed prodromal infection. Neuropsychiatric clinical complaints were different in children and adults. However, post-hospitalization recovery was similar between groups.

OBJECTIVE: To ensure the efficiency of the operation of the Emergency Department, specific mental health studies are needed. The purpose of the study was to identify and quantify the sociodemographic, clinical and organizational factors associated with the hyperfrequency of hospital Mental Health emergency departments in the three central areas of Asturias. METHODS: A retrospective case-control study was carried out. A total of 110 hyperfrequenters were recorded in 2017, based on a definition of five or more visits to the emergency department. The control group was composed of 170 subjects who attended on one occasion. In addition to descriptive analysis, Chi-square and ANOVA tests were used to identify differences between the two groups. A multivariate study was also carried out using binomial logistic regression. RESULTS: Hyperfrequent users were more likely to be young adult (30-44 years old), single, living with their family of origin, and with no jobs. The most prevalent diagnoses for these users were "Personality and Behavior Disorder" (F60-69) and "Schizophrenia, Schizotypal Disorders and Delusional Disorders" (F20-29). The most frequent reason for consultation was "anxiety/depression/somatization symptoms". The destination of the most frequent emergency was "Continue follow-up at scheduled appointments" and most consultations were made in the morning and on weekdays. CONCLUSIONS: Hyperfrequent users continue to demand attention despite being assigned one or more devices. Knowing their needs would help to improve healthcare and use resources more efficiently and effectively.
OBJETIVO: Para garantizar la eficiencia del funcionamiento del Servicio de Urgencias es necesario realizar estudios específicos de Salud Mental. El propósito del estudio fue identificar y cuantificar los factores sociodemográficos, clínicos y organizativos asociados con la hiperfrecuentación de las Urgencias Hospitalarias del Servicio de Salud Mental de las tres áreas sanitarias centrales de Asturias. METODOS: Se realizó un estudio retrospectivo de tipo casos-controles. Se registraron 110 hiperfrecuentadores en el año 2017, basándonos en una definición de cinco o más visitas al servicio de Urgencias. El grupo control lo compusieron 170 sujetos que acudieron en una sola ocasión. Además del análisis descriptivo, se utilizaron las pruebas Chi cuadrado y ANOVA para identificar diferencias entre ambos grupos. También se realizó un estudio multivariado mediante regresión logística binomial. RESULTADOS: Los usuarios hiperfrecuentadores eran más probablemente adultos jóvenes (30-44 años), solteros, convivientes con la familia de origen e inactivos laboralmente. Los diagnósticos más prevalentes para estos usuarios eran: "Trastorno de la personalidad y el comportamiento" (F60-69) y "Esquizofrenia, trastornos esquizotípicos y trastornos delirantes" (F20-29). El motivo de consulta más frecuente era "Síntomas de ansiedad/depresión/somatizaciones". El destino de la urgencia más frecuente fue "Continuar seguimiento en citas programadas" y la mayor parte de las consultas se realizaron en horario de mañana y en días laborables. CONCLUSIONES: Los usuarios hiperfrecuentadores continúan demandando atención a pesar de tener asignados uno o varios dispositivos de la red de salud mental. Conocer sus necesidades ayudaría a mejorar la atención sanitaria y a utilizar los recursos de manera más eficiente y eficaz.

PURPOSE: To describe the temporal association of specific acute neurological symptoms in pediatric patients with confirmed SARS-CoV-2 infection between May and August 2020. METHODS: We performed a recollection of all the clinical and laboratory data of patients having acute neurological symptoms temporally associated with SARS-CoV-2 infection at a third-level referral hospital in Mexico City (Instituto Nacional de Pediatría). Patients in an age group of 0-17 years with acute neurological signs (including ascending weakness with areflexia, diminished visual acuity, encephalopathy, ataxia, stroke, or weakness with plasma creatinine kinase (CK) elevation) were evaluated. RESULTS: Out of 23 patients with neurological manifestations, 10 (43%) had a confirmed SARS-CoV-2 infection. Among the infected patients, 5 (50%) were males aged 2-16 years old (median age 11.8 years old). Four (40%) patients confirmed a close contact with a relative positive for SARS-CoV-2, while 6 (60%) cases had a history of SARS-CoV-2-related symptoms over the previous 2 weeks. The following diagnoses were established: 3 cases of GBS, 2 of ON, 2 of AIS, one of myositis with rhabdomyolysis, one ACA, and one of anti-NMDA-R encephalitis. CONCLUSIONS: Neurological manifestations temporally associated with SARS-CoV-2 infection were noticed in the pediatric population even without respiratory symptoms. In this study, 2 of 6 symptomatic patients had mild respiratory symptoms and 4 had unspecific symptoms. During this pandemic, SARS-CoV-2 infection should be considered as etiology in patients with acute neurological symptoms, with or without previous respiratory manifestations, particularly in teenagers.

BACKGROUND AND OBJECTIVE: Demand from minors with complaints of gender dysphoria has increased in recent years. This increase has been more pronounced in adolescent trans men in some international research studies. The first objective of this research study was to determine the sex/gender ratio of minors requesting a consultation in the Gender Identity Treatment Unit of the Principality of Asturias (UTIGPA) and presenting complaints of gender dysphoria. The second objective was to analyse the relationship of the sex/gender ratio with the age variable at which they requested the first consultation and the year in which they requested it. MATERIALS AND METHOD: The sample consisted of 42 children under 18, attended between January 2016 and January 2019. The medical records were then reviewed to obtain information. Descriptive statistics were analysed with the collected data. RESULTS: The sex / gender ratio over the period was 2/1 in favour of trans men. The average age at the request for consultation was 15.02 years (SD=1.84), with a range of 6 to 17 years. A higher percentage of applications was recorded (35.7%) in 2018, mostly made by trans men (93.3%). CONCLUSIONS: There was an inversion of the sex/gender ratio, a favour of trans men, over the last 3years, and an increase in the number of applications by adolescent trans men, coinciding with several international investigations.

Resumo Introdução e objetivo: Ainda são escassos os estudos que avaliam com exatidão o sucesso do tratamento e retratamento endodônticos e quais as falhas que realmente impactam no desfecho dos mesmos. Determinar o índice e os fatores preditivos para o sucesso de tratamentos e retratamentos endodônticos, realizados por alunos de graduação com o mesmo nível de aprendizado. Materiais e métodos: Foram verificados os registros de proservação, com pelo menos 12 meses, dos tratamentos endodônticos realizados na Faculdade de Odontologia de Pelotas, analisando o sucesso ou o fracasso endodôntico, de acordo com critérios clínicos e radiográficos. As variáveis preditivas no resultado do sucesso do tratamento foram: dente, número de canais, coroa dentária, sintomas, diagnóstico da polpa e índice periapical radiográfico. As variáveis relacionadas ao tratamento foram: técnica de instrumentação, número de sessões e limite de instrumentação apical. Resultados: 136 tratamentos endodônticos foram realizados com um acompanhamento de, pelo menos, 12 meses. A avaliação mostrou que o sucesso endodôntico foi influenciado pelo número de sessões (P = 0,015), diagnóstico inicial e grupo dentário (P= 0.014). Também foi possível observar que, quanto maior o índice periapical radiográfico inicial, pior o prognóstico endodôntico (P < 0.001). Conclusão: O índice de sucesso do tratamento endodôntico foi de 96.7% para casos de polpa vital, 87.5% para os casos de necrose pulpar e 92.9% em retratamentos. Estes índices foram influenciados pelo dente tratado, diagnóstico inicial, índice periapical radiográfico inicial e pelo número de sessões utilizadas no tratamento.
Abstract Introduction and objective: There are still few studies that accurately address endodontic success and which failures actually impact the endodontic treatment outcome. Determine success rate and predictive factors for successful endodontic treatment and retreatment by undergraduate students of the same learning level. Materials and methods: The preservation records (12 months) of the endodontic treatments performed in the Faculty of Dentistry of Pelotas were verified, indicating the success or failure of the treatment. Predictive variables in the outcome of successful endodontic treatment or retreatment were: tooth, number of channels, dental crown, symptoms, pulp diagnosis, radiographic periapical index. The treatmentrelated variables were: instrumentation technique, number of sessions and apical instrumentation limit. Results: 136 endodontic treatments were performed with a follow-up of at least 12 months. The evaluation showed that endodontic success was influenced by the number of sessions (P = 0.015), initial diagnosis and dental group (P = 0.014). It was also observed that the higher the initial radiographic periapical index, the worse the endodontic prognosis (P < 0.001). Conclusion: The success rate of endodontic treatment was 96.7% for cases of vital pulp, 87.5% for cases of pulp necrosis and 92.9% for retreatments. These indices were influenced by type tooth, initial diagnosis, initial radiographic periapical index and the number of visits used in the treatment.
Resumen Introducción y objetivo: Todavía hay pocos estudios que aborden con precisión el éxito endodóntico y cuáles fracasos realmente impactan el resultado del tratamiento endodóntico. Determinar la tasa de éxito y los factores predictivos para el tratamiento y el retratamiento exitoso de endodoncia por estudiantes universitarios del mismo nivel de aprendizaje. Materiales y métodos: Se verificaron los registros de conservación (12 meses) de los tratamientos de endodoncia realizados en la Facultad de Odontología de Pelotas, lo que indica el éxito o el fracaso del tratamiento. Las variables predictivas en el resultado de un tratamiento o retratamiento endodóntico exitoso fueron: diente, número de canales, corona dental, síntomas, diagnóstico pulpar, índice periapical radiográfico. Las variables relacionadas con el tratamiento fueron: técnica de instrumentación, número de sesiones y límite de instrumentación apical. Resultados: se realizaron 136 tratamientos de endodoncia con un seguimiento de al menos 12 meses. La evaluación mostró que el éxito endodóntico estaba influenciado por el número de sesiones (P = 0.015), el diagnóstico inicial y el grupo dental (P = 0.014). También se observó que cuanto mayor es el índice periapical radiográfico inicial, peor es el pronóstico endodóntico (P <0.001). Conclusión: La tasa de éxito del tratamiento endodóntico fue del 96.7% para casos de pulpa vital, 87.5% para casos de necrosis pulpar y 92.9% para retratamientos. Estos índices fueron influenciados por el tipo de diente, el diagnóstico inicial, el índice periapical radiográfico inicial y el número de visitas utilizadas en el tratamiento.
